The poor documentation is an inconvenience, but the real problem is how often the functionality of the API changes (ie: breaks) without anyone at Facebook noticing (or perhaps just not caring). I remember constant problems with authentication and sharing APIs. How do you not have tests for those? Facebook is still way too cowboy.
